NYT Cooking: Steaming a whole fish is an excellent, and speedy, way to cook. The fish here, dabbed with ginger and a few other aromatics, is transformed by the process, and delivers a sweet, near-melting succulence. The pan juices are the only sauce necessary. A traditional bamboo steamer is great to have, but any sizable steamer will work, or you can rig up a steamer using a large pot. Make sure that the makeshift rack sits an inch or so above the boiling water, and that the pot has a lid.
